Popis:	This study evaluated the accuracy of a Dairy Herd Improvement Association test compared with bacterial culture to report the prevalence of chronic intramammary infections in dairy cattle. The Association classification considers a cow to have a chronic intramammary infection when her linear score is 4 or greater for more than one test in a lactation. The threshold level of linear score 6 minimized the sum of the misclassification errors. The Association test was not sensitive or specific enough compared with bacterial culture to classify individual cows accurately.
